The mining intrinsically safe type latched amplified phone circuit device can be used for voice communication, and also can be used for shutting down and latching devices (such as a motor) while being matched with various electric control devices, so that safety of personal and devices can be guaranteed, and peripheral devices can be controlled.
Description
Technical field
The utility model relates to a kind of hands free telephone, specifically is a kind of mining intrinsic safety type enclosed type hands free telephone circuit arrangement, and this hands free telephone is applicable to rubber conveyer working face under the coal mine, getting working face communication and control use.
Background technology
At present, the quantity of China's coal-mine down-hole belt feeder is quite a lot of, and the control section of belt feeder mostly is components and parts (as: contactor, the relay etc.) composition of separation greatly.This control appliance volume is big, failure rate is high, maintenance is inconvenient, especially in down-hole transportation, very inconvenient when installing.
In addition, existing mining down-hole public address set is difficult to carry out supporting use with various electrical control gears, more can not shut down and locking equipment, and the safety that ensures the person and equipment is brought hidden danger.
Summary of the invention
The utility model purpose is in order to overcome above-mentioned defective, provide a kind of compact conformation, volume little, transport, install, debug enclosed type hands free telephone easily.
The technical solution of the utility model is:
A kind of mining intrinsic safety type enclosed type hands free telephone circuit arrangement, comprise 18V intrinsic safety electric source module, charging control circuit, speech amplifier, get output module ready, front end voice amplification module and signaling switch processing module, described 18V intrinsic safety electric source module connects charging control circuit by binding post, charging control circuit connects speech amplifier respectively, get output module ready, front end voice amplification module and signaling switch processing module, the voice signal output of signaling switch processing module connects speech amplifier, speech amplifier connects loud speaker, the signaling switch processing module connects device for dotting by getting button ready, and the signaling switch processing module connects device for dotting by press-to-talk switch.
The signal input part of described signaling switch processing module connects the voice signal line.
The beneficial effects of the utility model are:
Enclosed type hands free telephone circuit arrangement of the present utility model, be mining intrinsic safety electro gas equipment, be applicable to the environment that gas, coal dust explosion hazard are arranged under the coal mine, also be applicable to adverse circumstances such as metallurgy, building materials, mine and coal preparation plant, steel plant, cogeneration power plant, harbour.Can be used for speech communication and various electrical control gear when supporting, can shut down and locking equipment (as motor) again, guarantee the safety of the person and equipment, can also control external equipment etc.
Of the present utility model can being widely used in has in the environment of damp (methane) and coal dust, and it is simple to operate, and is easy to use.As long as press " sending words " button during use, can carry out single worker's conversation; Press " locking " button left, the right rotation button, can realize locking, send one simultaneously and often open no electric potential contact signal.The button opposite spin, make that red point on the button is aimed at red point on the outer rim after, button is extracted can be realized release again.
Description of drawings

Fig. 2 is the wiring schematic diagram of binding post of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
A kind of mining intrinsic safety type enclosed type hands free telephone circuit arrangement, comprise 18V intrinsic safety electric source module, charging control circuit, speech amplifier, get output module ready, front end voice amplification module and signaling switch processing module, described 18V intrinsic safety electric source module connects charging control circuit by binding post, charging control circuit connects speech amplifier respectively, get output module ready, front end voice amplification module and signaling switch processing module, the voice signal output of signaling switch processing module connects speech amplifier, speech amplifier connects loud speaker, the signaling switch processing module connects device for dotting by getting button ready, and the signaling switch processing module connects device for dotting by press-to-talk switch.
The signal input part of signaling switch processing module connects the voice signal line.
Fig. 1 is an electrical principle block diagram of the present utility model.Supply power voltage is the 18V intrinsic safety electric source, binding post by Fig. 2 is introduced, phone comprises sending and is subjected to words parts, early warning to send part and the anxious latching segment of closing down, voice in the phone are accepted part and are being detected voice lines always, when the signal on the voice lines during less than 400mV, voice are accepted part and are quit work, when the signal on the voice lines time more than or equal to 400mV, voice receiving portion branch begins work, voice signal is amplified, send out by loud speaker, if signal is less than 400mV, the phone cut-out of will delaying time.When power line connected, phone was in charged state, and charging divides three gears: it is 18mA that first toggle switch is put in the ON position; It is 23mA that second toggle switch is put in the ON position; It is 34mA that first toggle switch, second toggle switch are all put in the ON position.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; do not breaking away under the utility model design concept prerequisite; common engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection range of the present utility model, the technology contents that the utility model is asked for protection all is documented in claims.
